application filed June '1, 1918. Serial No. 237,804.

This invention relates to improvements in' washing machines, and has for one of its objects to combine in one machine the advantages of a suction and rubbing action on the garments within a receptacle.

Another object of the invention is to provide a device of this character of improved construction and increased efliciency wherein the requisite movements of the combined suction and rubbing element is accomplished by actuating an operating leverext'ernally of the receptacle or tub for the garment.

Another object of the invention is to provide a device of this character wherein the parts arereadily assembled and which may be separated for renewal or repairs of impaired portions without discarding the remaining portions.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a vertical sectional elevation,

Fig. 2 is a plan view,

Fig. 3 is a bottom plan view of the combined suction and. rubbing portion of the device, c

Fig. 4 is a side elevation illustrating the arrangement of the operating lever mechamsin,

Fig. 5 is a detached perspective view of the oscillating arm.

The improved device may be arranged in connection with any desired form of tub or receptacle for the garments, but for the purpose of illustration 'an ordinary round or circular tub is shown and indicated as a whole at 10. The receptacle is suitably mounted upon supporting legs indicated at 11 and provided with a detachable closure 12 hingedly united to the body of the tub at one side, as shown.

Disposed upon the top 12 centrally thereof isa supporting bracket including a bearin 13 to support the upper end of a standar or shaft 14. Thestandard 14 extends into the interior of the body 10 and is then directed at an angle to the vertical axi of the portion 14 of the standard as shown at 16.

Mounted for rotation upon the portion 16 of the standard is a combined rubbing and suction producing device comprising a shell portion 17 open at the lower side. Mounted upon the closed side of the shell 17 is a tubular socket device 18 having alaterally directed flange 19 bearing upon the outer face of the shell. The socket device 18 extends through the shell and in advance of its lower open face, the obliquely directed portion 16 of the standard extending through the socket and held against with.-

drawal by a transverse pin 20 inserted through it adjacent the end of the socket. Fitting over the protruding terminals of the socket and of the standard is a rubbing block-21 having a lateral flange 22 at its in-' ner end corresponding substantially to the flange 19 of the socket. The flanges 1922 are coupled by a plurality of tie rods 23 so that the shell is firmly coupled to the socket. The pin 20, by engaging against the end of the socket, prevents withdrawal of the standard from the socket.

Disposed Within the shell 17 are a plurality of radially extendin partitions 24'forming a plurality of independent compartments'within the shell as illustrated in Fig. 3. At their inner ends the partitions 24 bear against the outer face of the socket 18 and conform in outline to the inner face of the shell 17. At their outer ends the partitions depend below the line of the dhell and are formed with recesses 25 in their lower edges whereby rubbers 26 are produced. The partitions are secured in place by screws or like devices 27 passing through the side of the shell into the'ends of the partitions, and

the lower edges of the partitions, at their be swung around the vertical axis of the standard in aninclined position and caused to roll over the clothes in the tub, rotating about its own axis in the direction opposite to the direction, of rotation of the standard, thus bringing the compartments formed by lowest point.

the partitions consecutively Formed through the upper end of the shell 17 between the partitions 24 are openings 28. In the illustration shown in Fig. 3 six of the radial partitions 24 are shown, thus producing six compartments within'the dolly and each compartmentis provided with an opening 28. Attached to the outer face of the shell and extending over each alternate opening 28 is a cage 29 in which a valve 30 is disposed and operates to close the upper side of the opening. Attached to the inner face of the shell and extending over each of the remaining. alternate openings 28 is a similar cage 31, and disposed within each of the cages 31 is-a similar valve 32 operating to bear over the inner side of the adjacent opening 28. 'Thus ones'half of the compartments are provided with outwardly opening valves and the remaining half of the compartments provided "with inwardly opening valves. 2

"The compartments .operate -as air cups, andas the shell is rotated the compartments or cups move downwardly against the garments and into the water at one side and.

rise above the Water and away from the arset up a very thorough circulation of the,

water through the compartments and the clothes and cause-the clothes to be sucked into the alternate compartments! whereby they will be drawn across the rubbers and agitated throughout their mass, the dirt being rapidly removed.

Connected to the portion 14 of the standard. externally of the top 12 of the receptacle is a gear pinion 33, and surrounding the pinion and connected to the bearing 13 is a cage-like structure 34. Connected to the body 10 of the receptacle at one side and near the upper and lower portions are bracket devices 35 through which a vertical shaft 36 is mounted for rotation.

Attached to the free edge of the closure 12 is'a bracket 54 having a bearing sleeve 55 at its outer end, the center of the hearing sleeve being in alinement with the shaft 36 and receiving the upper end of the latter. Disposed above the bearing-sleeve 55 is into their an arm 37 having a depending hub 56 rotatably engaging in the bearing sleeve 55. The shaft 36 is provided with a transverse pin 57 extending through the shaft and engaging in transverse recesses or seats 58 in the hub 56. By this arrangement the arm 37 is rotatably mounted upon the sleeve 55 of the bracket 54 and moves with the closure 12 when the latter is disposed in open position, and is automatically coupled to the shaft 36 when the closure 12 is in its downward position as shown in Fig. 1. The shaft 36 remains in position supported by thebearings 35, and the arm 37 is moved away from the shaft with the closure 12 when the latter is disposed in open position. Pivoted at one-end to the arm 37 is an operating bar 38 having a rack 39 engaging. the pinion 33 at one side. Pivoted to the arm 37 at the opposite end is a bar 40 having a rack 41 engaging the pinion 33' at the opposite side. The bars 3840 operate one above the other, and the pinion 33 is. of suflicient length to permit the bars to thus operate thereon without interference. The cage 34 is preferably provided with vertically directed guide portions 4243 having guideways to respectively receive the bars 38- 40. The bars 3840 are preferably provided respectively with vertical guide ribs 44' 45 which engage through seats in the guideways 4243. By this means the bars are maintained in proper position relative-to the pinion, and operate without cramping. The seats in the members 4243 are formed with curved contiguous faces as indicated by dotted lines arrangement it will be obvious that whenthe lever 51 is vibrated upon its pivot 49,

the rod 48 will correspondingly oscillate the arm 47 and the shaft 36 and thus produce alternate rotary motion to the shaftmember 14, and alternately rotate the shell 17 and its attachments.

'The parts are so proportioned that each vibration of the lever 51 will cause the shell 17 to alternately complete a full revolution at each movement.

The improved apparatus is effectual in operation, can be inexpensively manufactured and produces a rapid alternating suction and compression action upon the 4 clothes. The water is thus drawn through the garments by' the suction at one side of the shell.

Having thus described the invention, what is claimed as new is:

.1. A washing machine comprising a shaft mounted for rotation and having a portion extending obliquely to the longitudinal axis thereof, a shell mounted for rotation on the obliquely directed portion of the shaft and divided by radial partitions into a plurality ofdownwardly opening air chambers whereby the chambers are consecutively com pressed against the garments and elevated therefrom, an inwardly opening valve connected to each alternate air chamber, and

an outwardly opening valve connected to each of the remaining alternate air chambers.

2. A washing machine comprising a shaft mounted for rotation and having a portion extending obliquely to the longitudinal axis thereof, a tubular support rotative on the obliquely directed portion of the shaft and including a lateral flange, a shell engaging said flange, a rubbing block bearing over the inner end of the shaftfa plurality of partition members radially disposed within the shell and bearing at their inner endsagainst the tubular member whereby a plurality of air chambers are formed, an inwardly opening valve connected to each alternate air chamber and an outwardly opening valve connected to each of the remaining alternate air chambers, and clamping devices connecting the flange of the tubular member to the rubbing block.

3. A washing machine comprising a shaft mounted for rotation and having a portion extending obliquely to the longitudinal axis thereof, a shell mounted for rotation on the obliquely directed. portion of the shaft and divided by radial partitions into a plurality of downwardly opening air chambers whereby the chambers are consecutively compressed against the garments and elevated therefrom, an inwardly opening valve connected to each alternate air chamber, an outwardly opening valve connected to each of the remaining alternate,

air chambers, and means for oscillating said shaft.

In testimony whereof I affix my signature;
